   % Problem statement
   Write an equation system that is equivalent to the vector equation:
	 \begin{center}
		  $x_1\begin{pmatrix}3 \\ -2 \end{pmatrix}+x_2\begin{pmatrix}7 \\ 3 \end{pmatrix}+x_3\begin{pmatrix}-2 \\ 1 \end{pmatrix}=\begin{pmatrix}0 \\ 0 \end{pmatrix}$
	 \end{center}
}{
   % Solution
	We may write the following equation system (in matrix form):
	\begin{center}
		$\begin{pmatrix}3 & 7 & -2 \\ -2 & 3 & 1\end{pmatrix}\begin{pmatrix} x_1 \\ x_2 \\ x_3 \end{pmatrix}=\begin{pmatrix}0 \\ 0 \end{pmatrix}$
	\end{center}
